Pigment Web Site

For all the pigments we discussed in the Alchemy of Pigment workshop, I found a wonderful web site that has all the colors from minim to lapis lazuli to Egyptian blue to orpiment.

Egyptian blue pigment from Natural Pigment website. Egyptian Blue is a copper calcium silicate that was the first synthetic pigment and the most extensively used from the early dynasties in Egypt until the end of the Roman period in Europe.

Next is orpiment pigment powder from Natural Pigments .Orpiment is yellow arsenic sulfide, a rare mineral usually described as a lemon or canary yellow or sometimes as a golden or brownish yellow. Our orpiment is an intensely bright pigment of crystalline particles from Kyrgyzstan.

Warm cinnabar pigment from Natural Pigmentsprepared from ore deposits near Nikitovka in the Doneckaia region of Ukraine. It exhibits a beautiful masstone color of strong red with a tendency toward reddish orange.Minium pigment from Natural Pigment website (seen below). Minium, also known as "surik" or "surick" (Russian), is red lead, an oxidation product of lead minerals. It is an intense orange red that is opaque and works well in oil and egg tempera.

Armenian purple ochre pigment from Natural Pigments. Armenian Purple Ocher is a natural earth containing clay tinted by iron oxide that gives an exceptionally cool red hue. Purple Ocher is obtained from iron ore deposits near Lori, Armenia.I had previously ordered powder pigments from Earth Pigments but Natural Pigments has a grater variety. However, the former site is pretty safe in terms of non toxic. Natural Pigments does offer some highly toxic colors as in the orpiment, cinnabar, minim, realgar and other derivatives from arsenic, mercury and lead. Use caution.

This naughty little drawing might have merited the extreme displeasure of Hatshepsut had she seen it. But when was this pornographic cartoon made? Could it have been at the time of her successor, Thuthmose III? Or was it truly from the time of Hatshepsut with rumors rampant about her favored vizier, architect and tutor for her daughter Neferure? At any rate, it is pretty graphic and unsanctioned paving the way for my comments and images of Greek and Roman graffiti of phalluses and comments about women.

Some graffiti historians believe that markings making a statement, message or sign can trace their origin to prehistoric times, up to 30,000 BCE. However, this is likely a stretch of the imagination when we don't even know that much about the motives of the mark makers in a period when there was no writing. Scratchings and incised lines on cave and rock shelter walls along with red ochre, manganese and chalk images are probably not meant as propaganda; they may have had some spiritual meaning in the way that a shaman would represent a :vision quest" of some sort. Circa 3000 BCE in some parts of the world - writing started with pictographs and then around 1900-1700 BCE actual writing can be deciphered. More often, images such as the one above confer the idea of poking fun of a situation or person. They aren't dated which makes it difficult to assess. However, one can imagine a rebellious teenage Egyptian boy marking up the temple of the Pharaoh Seti I with his crude dra…

Bansky's West Bank images from his trip to Israel came about as a social commentary about the controversial wall that separates Israeli citizens from Palestinian. As seen above, the dove holding an olive branch, symbol of peace, is wearing a flak jacket with a target in red as it would appear behind the
focusing element of an AK 47 or other semi-automatic rifle as that seen held in the arms of the Israeli soldier. Bansky created a total of 9 graffiti art images on the 425 foot "security" wall that the United Nations has declared as unlawful - the wall, that is. The wall was discussed at my visit to the U.S. Consulate in July 2007 on a Fulbright Hays Summer Seminar to Egypt/Israel for six weeks. We were told that we couldn't go to Bethlehem or other sites in the West Bank for security reasons. It's too bad since I could have witnessed this remarkable collection of art produced by Bansky in person. While in Israel, I was aware of the tensions and felt especia…

I've traveled extensively since 1981 from England to Cambodia, Egypt, Sicily, South and Central America and back to the UK. sharing the stories of others and their successes despite adversity, their creativity, their humor and yes, sometimes sadness links me to the world of humanity and increases my love and compassion for everyone. Travel, for me, makes my world brighter and fills my mind with possibilities and hope. I've learned valuable lessons through travel and the people I have met.
